(54)	Output adjustment for digital printers

(57) A method for providing information usable for adjusting the output of a digital printer, includes the steps of providing a plurality of known code values to the digital printer which produces a test print including a plurality of test patches of density; and providing a plurality of reference patches each having an aim density. The method further includes scanning both the test patches and the reference patches to produce code values of both the test patches and the reference patches; and comparing the code values of the scanned test patches and the reference patches to determine the correspondence between the test patches and the reference patches and to provide information adapted to be used for digital printer output adjustment.
